Bit of a necromancing action here (only two months since the last post) but I found the relevant bits I'd recalled when I posted on the first page.
Havenite enlisted & noncommissioned officers were heavy on conscripts, during the Legislaturalist & Committee eras.

Echoes of Honor, Ch 40 wrote:Of course, Phillips came from a very different naval tradition—that of the Sarawak Republic, one of the liberal-thinking targets the Peeps had gobbled up in the early days of the DuQuesne Plan. The SSN had relied upon a professional officer corps, but Sarawak's advanced, egalitarian social theories had inspired it (unlike the dangerous, elitist plutocracy of Manticore) to use short-service conscripts to fill its enlisted and noncommissioned ranks. The result had produced something very like the present-day People's Navy, in which the service simply hadn't had its enlisted draftees long enough to train them up to Manticoran standards. Which meant that Phillips' ingrained belief that officers ought to be better at their jobs than petty officers represented her own experience, not blind prejudice.
Bolded the critical portion of the passage. So up until Honor's mass breakout from Hell, the Republic Navy had a small professional officer corps, and conscripts even before the Proles started voluntarily enlisting.
Now I think there's other existing text evidence, regarding the Havenite Marines from tSVW when Kevin Usher was part of the assassination squad that killed the head of InSec Constance Palmer-Levy that the Havenite Marines were also conscript heavy.
Which means short of any evidence otherwise, the only truly non-conscript portion of the Havenite military would be their Army/Pacification units; which actually makes a lot of sense. Given their duties, you'd only want people who wanted to be there doing that kind of work, even doing it; so I figure this is actually where the bulk of the future StateSec came from after StateSec ingested all other forms of security and militaries short of the Navy & Marines.
